Product description
Active barrier Endress+Hauser RN42-AA1BU
The RN42-AA1BU (RN42-10A1/0) 1-channel active barrier from Endress+Hauser with wide-range power supply is used for the safe electrical isolation of signals ranging from 0 or 4 to 20 mA. The device has a feed/non-feed current input to which a 2-wire transmitter can be directly connected. The device output can be operated actively or passively. Connection lugs for connecting HART communicators are integrated in the front of the device. The RN42-AA1BU supply isolator with a supply voltage ranging from 24 to 230 V AC/DC can be mounted on a DIN35 rail and is connected push-in terminals.
